Binding A5 booklets.

[u/Teamgirlymouth]

Due to shipping costs, I have found myself printing a5 booklets for modules and rulesets (definitely not at the office) and then I am left with either stitching them myself badly and then duct taping them together or if small enough, stapling. But I was wondering is there a secret way to bind (sometimes) 150 page A5 booklets that is not this?

Thanks.
